Aaron Nola of the Philadelphia Phillies was third with 86 points, followed by Colorado's Kyle Freeland and Arizona's Patrick Corbin. Nine runs and four homers in 13.1 innings across three starts.
He earned 17 first-place votes and 169 points in voting.
DeGrom, 30, had just 10 wins, fewest ever by a Cy Young-winning starting pitcher in a full season, for a Mets club that finished eight games under.500.
That 1.70 ERA, however, was the sixth-lowest posted by any major league pitcher since the mound was lowered in 1969, and voters weren't about to gloss over that fact.
In siding overwhelmingly with deGrom, voters made perhaps the strongest declaration to date that the notion of evaluating pitchers by their win total is no longer viable.
Thus did Scherzer, whose 2.53 ERA ranked third in the NL behind deGrom and Nola (2.37), come up short in his quest for back-to-back-to-back Cy Young Awards, a feat previously achieved only by Greg Maddux and Randy Johnson. Indians ace Corey Kluber finished a distant third with 71 points. "I'm extremely humbled to win this award along with some other great former Mets such as Tom Seaver, Dwight Gooden and R.A. Dickey". Only 26 AL pitchers threw enough innings to qualify for the ERA title this year.
The 52nd overall pick in the 2011 draft from Shorewood High School in Seattle, Snell reached the majors in 2016 but struggled at the outset of 2017 and returned to Triple-A for seven starts.
DeGrom has received Cy Young votes in two prior seasons but had never finished in the top five. And it's what made voting for this year's NL Cy Young victor a privilege. That was the lowest mark since Zack Greinke's in 2015, and the second lowest in the last 23 seasons in Major League Baseball.
Kluber was attempting to win his second straight Cy Young and third overall.
